CHARLES TORCHEBEUF AND EDGARD DE LANNEAU, OF PARIS, FRANCE.

CARBURETING-LAMP.

Application filed June 7,

To all "whom it may concern.'

Be it known that we, CHARLES TORCHE- until# and Eooxnn nn LANNEAU, citizens of as ordinary carbureting liquid or hydrocarbons.

The invention is illustrated in the annexed drawing in which Figure 1 is a longitudinal section of the contrivance showing the essential elements and particularly the novel features of the burner. Fig. 2 is a section along the line A-A of Fig. 1, and F ig. 3 is a section along the line B-B of Fig. 1.

The characteristic feature of this burner 1s that it comprises for feeding purposes an absorbent mass 2 of incombustible mat-ter, such as flexible asbestos for example, continuously moistened with the carburetin0r liquid by a wick 1 of incombustible material, the upper part of which is incorporated with the said mass. This latter, which is preferably molded into the form of a disk or short cylinder is pierced with a plurality of holes 3 for the passage of the air to be carbureted. The absorbent mass 2 is inclosed within a case 12 which preferably is a good conductor ef heat, the case being situated immedlately beneath the mixing chamber 1l in such a manner as to be heated as directly as possible by the heat given out by the flame. The heating of the absorbent mass is in addition greatly facilitated by a body 4 which 1s a good conductor of heat and which is situated at the axis of the mixing chamber with its lower end, which is branched, inserted into the said absorbent mass, while lts upper end projects above the metallic cover 13 of the chamber. In the form of construction shown, the conductive body consists of a metallic rod 4 o.' a plurality of wires suitably bent at their lower ends and umted to form a single vertical rod as shown in the drawing.

The case 12 which may be integral with 1l. which serves as the combustion and the mixmg chamber, is carried on a suitable base 14 0f which the lower part is screw- Specticaton of Letters Patent.

threaded to allow of the burner being secured to a reservoir of combustible liquid into which the wick l dips. A guide tube l5 incloscs the wick and centers it iu the base 14. In the wall of the latter, above the screw-threaded portion, are situated openings 5 the size oi which can be regulated by means of a ring 16 provided with corresponding openings 17. This outer ring can be replaced by means of two rods 1S secured thereto.

TNithin the case 12, above the molded absorbent niass 2, are formed a series of oriices 6 of variable number and size according to the type of burner employed. On a level with these orifices there is fitted within the case 12 a flanged washer 7 serving on the one band to maatain the mass 2 securely fixed within the base, and on the other hand to prevent the outside air from finding direct entrance through the orifices G, thus facilitating the obtainment of a steady light.

The base of the mixing chamber preferably comprises a truncated conical portion to which is secured the support 8 of the suspension rod of the mantle.

The new burner, as in the majority of known burners, comprises a gallery 9 which serves to carry the chimney 10.

The wick l and the iiat cylinder 2 being impregnated with the carbureting liquid, and the orifices 5 being fully open, the ignition will be effected by introducing into the chimney from above or below, a match or a pad saturated with alcohol. The draft which will resultwill draw in the air which, passing through the orices 5, will be carbureted in traversing the orifices 3 of the mass 2. The external air will also enter through the orifices 6 and rise directly to the mantle without passing through the orifices 3. These oritices, whose size is invariable, lessen the proportion of carbureted air entering through the orifices 5, and produce a mixture oi carbureted air which burns with a blue flame. The rod 4 will be raised to a high temperature, and by conduction will transmit to the vaporizer 2, heat suiicient to vaporize the combustible liquid contained therein. The walls of the case 12 formed by the base of the burner tube, will also convey heat to the vaporizer, and this heat will be added to that of the rod. The carburization of the air thus occurs at a temperature high enough to be independent ci outside influence. To extinguish the light it is only neessury to close the openings 5 completely,"und to lnve them in this position in order to avoid evaporation of the combustible liquid.
